The invention relates to the technical field of box girder hoisting, in particular to a large-span box girder hoisting safety protection device which comprises a box girder, and a mounting mechanism is fixed to the box girder. A support upper steel plate is fixed on the mounting mechanism; a plurality of damping mechanisms are mounted on the support upper steel plate; a base plate is fixed on the damping mechanism; a supporting mechanism is mounted on the base plate; limiting mechanisms are fixed on the box girder and the base plate; through the mounting mechanism, the steel plate on the support can be fixed at the bottom end of the box girder, so that the limiting mechanism can be in contact with the box girder conveniently; vibration is generated in the installation process of the box girder, then the box girder drives the steel plate on the support to move, then the damping mechanism absorbs the acting force generated by the box girder, and the box girder is prevented from being broken. The steel plate on the support drives the limiting mechanism to slide, so that impact force borne by the base plate can be dispersed by the supporting mechanism, and a sufficient safe operation space can be reserved for the hands of a worker during operation.

    本发明涉及箱梁吊装技术领域,具体的说是一种大跨度箱梁吊装安全防护装置,包括箱梁,所述箱梁上固定有安装机构;所述安装机构上固定有支座上钢板;所述支座上钢板上安装有若干个减震机构;所述减震机构上固定有垫板;所述垫板上安装有支撑机构;所述箱梁和垫板上均固定有限位机构;通过安装机构,可以将支座上钢板固定在箱梁的底端,进而便于使限位机构与箱梁接触;箱梁安装过程中产生振动,进而使其带动支座上钢板位移,进而使减震机构对箱梁产生的作用力进行吸收,有利于防止箱梁折断;支座上钢板带动限位机构滑动,可以使垫板受到的冲击力被支撑机构分散,可以使工人在操作时手部留有充分的安全操作空间。
